Natto Spores (aka Natto-Moto) is the starter culture used with soybeans to make traditional Japanese natto-kin. You can make natto-kin (or natto for short) fresh at home. This powdered starter spore culture comes with complete Japanese instructions and a special measuring spoon. We have the English translation at our web site: How to make Natto...Natto Kin Spores

The process is a little difficult, but not to hard once you have completed the process a few times. It starts by inoculating cooked soy beans with the natto spores. This incubates in a warm place in serving size container for 12 to 24 hours. Once inoculation is complete you now have made natto-kin. Freeze extra containers, pull, and thaw for use.
